The U.S. agency that reviews medicine products is the Food and Drug Administration, or FDA.

Cosmetic cream
Most cosmetics can be sold without FDA approval. Ingredients used to add color, such as dyes, need FDA approval.
Drug rules apply to a cream if its claims include treating disease or changing the way the body works, even if it also changes appearance.
Ask what the product is claimed to do.
Approved medicine
Semaglutide (Ozempic, Wegovy) has FDA approval for specific uses.
Approval concerns a particular product and use, not every treatment called a peptide.
Ask for the medicine’s name and intended use.
Medicine made to order
In compounding, a medicine is prepared to order. It is not supplied as a finished product made in a factory.
These made-to-order medicines have no FDA approval. Before they are sold, the agency does not review their quality, how well they work or their possible harms.
An approved medicine may leave a patient’s medical need unmet. A made-to-order medicine may fill that gap, but federal rules for preparing and supplying it still apply.
A dye allergy may rule out the ready-made medicine for a patient. Another patient may be unable to swallow a tablet.
Ask the pharmacist why an approved medicine will not meet your need and whether the made-to-order medicine meets those rules.
